  • The best way to structure/design game code

    - by Edward
    My question is quite broad and related to the 2D game code design/architecture/structure. Usually the main game consists of the main loop where you update & render your world states. However, it's recommended for many purposes to separate rendering from the game-logic and so on. I am kinda confused about the whole situation. Many game engines/libs/sdks don't follow separation schema. They propagate a way where you define some scenes/stages and they contain some objects and the scene/stage controls the user input and so on. For example, in cocos2d(-x) and libgdx (stage2d) the games are usually done the way that the update logic happens at the same time/place as rendering. Also, the propagated way is to have a structure where an object knows how to draw itself - which is not a separation of updating & rendering. The same with Flash based games, they are usually done the way when an object (class) contains a swf or a texture and some data and holds some update logic itself, or updated from main Scene. And again this object already knows how to draw itself via "addChild". Also, some people recommend to use MVC pattern, which will require to completely obey the structure of those engines/libs/sdks. Maybe I am overthinking everything, but I am totally confused. I would be grateful if somebody could point me to a correct direction with the game code structures. What is your way of doing things in libgdx/cocos2d/flash?

  • Design guideline for saving big byte stream in c# [migrated]

    - by Praveen
    I have an application where I am receiving big byte array very fast around per 50 miliseconds. The byte array contains some information like file name etc. The data (byte array ) may come from several sources. Each time I receive the data, I have to find the file name and save the data to that file name. I need some guide lines to how should I design it so that it works efficient. Following is my code... public class DataSaver { private static Dictionary<string, FileStream> _dictFileStream; public static void SaveData(byte[] byteArray) { string fileName = GetFileNameFromArray(byteArray); FileStream fs = GetFileStream(fileName); fs.Write(byteArray, 0, byteArray.Length); } private static FileStream GetFileStream(string fileName) { FileStream fs; bool hasStream = _dictFileStream.TryGetValue(fileName, out fs); if (!hasStream) { fs = new FileStream(fileName, FileMode.Append); _dictFileStream.Add(fileName, fs); } return fs; } public static void CloseSaver() { foreach (var key in _dictFileStream.Keys) { _dictFileStream[key].Close(); } } } How can I improve this code ? I need to create a thread maybe to do the saving.

  • (Abstract) Game engine design

    - by lukeluke
    I am writing a simple 2D game (for mobile platforms) for the first time. From an abstract point of view, i have the main player controlled by the human, the enemies, elments that will interact with the main player, other living elements that will be controlled by a simple AI (both enemies and non-enemies). The human player will be totally controlled by the player, the other actors will be controlled by AI. So i have a class CActor and a class CActorLogic to start with. I would define a CActor subclass CHero (the main player controlled with some input device). This class will probably implement some type of listener, in order to capture input events. The other players controlled by the AI will be probably a specific subclass of CActor (a subclass per-type, obviously). This seems to be reasonable. The CActor class should have a reference to a method of CActorLogic, that we will call something like CActorLogic::Advance() or similar. Actors should have a visual representation. I would introduce a CActorRepresentation class, with a method like Render() that will draw the actor (that is, the right frame of the right animation). Where to change the animation? Well, the actor logic method Advance() should take care of checking collisions and other things. I would like to discuss the design of a game engine (actors, entities, objects, messages, input handling, visualization of object states (that is, rendering, sound output and so on)) but not from a low level point of view, but from an high level point of view, like i have described above. My question is: is there any book/on line resource that will help me organize things (using an object oriented approach)? Thanks

  • Class Design - Space Simulator

    - by Peteyslatts
    I have pretty much taught myself everything I know about programming, so while I know how to teach myself (books, internet and reading API's), I'm finding that there hasn't been a whole lot in the way of good programming. So I have two questions: First the broad one: Does anyone have suggestions as to sources for learning about good programming habits and techniques? I'd prefer it if the resource wasn't a 5000 page tome. The more I can read it in installments the better. More specifically: I am finishing up learning the basics of XNA and I want to create a space simulator to test my knowledge. This isn't a full scale simulator, but just something that covers everything I learned. It's also going to be modular so I can build on it, after I get the basics down. One of the early features I want to implement is AI. And I want to take this into account as I'm designing my classes so I can minimize rewriting code. So my question: How should I design ship classes so that both the player and AI can use them? The only idea I have so far is: Create a ship class that contains stats, models, textures, collision data etc. The player and AI would then have the data for position, rotation, health, etc and would base their status off of the ship stats.

  • Object construction design

    - by James
    I recently started to use c# to interface with a database, and there was one part of the process that appeared odd to me. When creating a SqlCommand, the method I was lead to took the form: SqlCommand myCommand = new SqlCommand("Command String", myConnection); Coming from a Java background, I was expecting something more similar to SqlCommand myCommand = myConnection.createCommand("Command String"); I am asking, in terms of design, what is the difference between the two? The phrase "single responsibility" has been used to suggest that a connection should not be responsible for creating SqlCommands, but I would also say that, in my mind, the difference between the two is partly a mental one of the difference between a connection executing a command and a command acting on a connection, the latter of which seems less like what I have been lead to believe OOP should be. There is also a part of me wondering if the two should be completely separate, and should only come together in some sort of connection.execute(command) method. Can anyone help clear up these differences? Are any of these methods "more correct" than the others from an OO point of view? (P.S. the fact that c# is used is completely irrelevant. It just highlighted to me that different approaches were used)

  • Java game design question (graphical objects)

    - by vemalsar
    Hello Guys, I'm beginner in game development, in Java and here on this site too and I have a game design question. Please comment my idea: I have a main loop which call update and draw method. I want to use an ArrayList which store graphical objects, they have coordinate and image or text to draw and my game objects extends this class. In update, I can choose which objects should be put in the array and in draw method I'll display the elements of array on the screen. I'm using a buffer and draw first there, but it is not important now I guess...Here is a simple (not full) code, only the logic: public class GamePanel extends JPanel implements KeyListener { ArrayList<graphicalObjects> graphArray = new ArrayList<graphicalObjects>(); public void update() { //change the game scene, update the graphArray, process input etc. } public void draw() { //draws every element of graphArray to a JPanel } public static main(String[] args) { while(true) { update(); draw(); } } } My questions: Should have I use interface or abstract class for graphicalObjects? graphicalObjects class and the ArrayList really needs or there is some better solution? How to draw objects? They draw themself with their own method or in the draw method I have to draw manually based on graphicalObjects variables (x,y coordinates, image etc.)? If this conception is wrong, please suggest another one! All comments are welcome and sorry if this is dumb question, thanks!

  • Are there any good videos out there on Java Design Patterns?

    - by Becky Reamy
    My team would like to spend some time at lunch learning design patterns. Previously, we watched some videos on Javascript which we found very useful as a way to start discussions. We would like to do the same thing with design patterns so that we don't have to spend a lot of time (outside of work) researching individual patterns in order to give a presentation. I did a little searching and came up fairly empty handed. Any help would be appreciated. It doesn't even have to be a video, even something that we can listen to (maybe a book on tape even).

  • Overwhelmed by design patterns... where to begin?

    - by Pete
    I am writing a simple prototype code to demonstrate & profile I/O schemes (HDF4, HDF5, HDF5 using parallel IO, NetCDF, etc.) for a physics code. Since focus is on IO, the rest of the program is very simple: class Grid { public: floatArray x,y,z; }; class MyModel { public: MyModel(const int &nip1, const int &njp1, const int &nkp1, const int &numProcs); Grid grid; map<string, floatArray> plasmaVariables; }; Where floatArray is a simple class that lets me define arbitrary dimensioned arrays and do mathematical operations on them (i.e. x+y is point-wise addition). Of course, I could use better encapsulation (write accessors/setters, etc.), but that's not the concept I'm struggling with. For the I/O routines, I am envisioning applying simple inheritance: Abstract I/O class defines read & write functions to fill in the "myModel" object HDF4 derived class HDF5 HDF5 using parallel IO NetCDF etc... The code should read data in any of these formats, then write out to any of these formats. In the past, I would add an AbstractIO member to myModel and create/destroy this object depending on which I/O scheme I want. In this way, I could do something like: myModelObj.ioObj->read('input.hdf') myModelObj.ioObj->write('output.hdf') I have a bit of OOP experience but very little on the Design Patterns front, so I recently acquired the Gang of Four book "Design Patterns: Elements of Reusable Object-Oriented Software". OOP designers: Which pattern(s) would you recommend I use to integrate I/O with the myModel object? I am interested in answering this for two reasons: To learn more about design patterns in general Apply what I learn to help refactor an large old crufty/legacy physics code to be more human-readable & extensible. I am leaning towards applying the Decerator pattern to myModel, so I can attach the I/O responsibilities dynamically to myModel (i.e. whether to use HDF4, HDF5, etc.). However, I don't feel very confident that this is the best pattern to apply. Reading the Gang of Four book cover-to-cover before I start coding feels like a good way to develop an unhealthy caffeine addiction. What patterns do you recommend?

  • Help with C# program design implementation: multiple array of lists or a better way?

    - by Bob
    I'm creating a 2D tile-based RPG in XNA and am in the initial design phase. I was thinking of how I want my tile engine to work and came up with a rough sketch. Basically I want a grid of tiles, but at each tile location I want to be able to add more than one tile and have an offset. I'd like this so that I could do something like add individual trees on the world map to give more flair. Or set bottles on a bar in some town without having to draw a bunch of different bar tiles with varying bottles. But maybe my reach is greater than my grasp. I went to implement the idea and had something like this in my Map object: List<Tile>[,] Grid; But then I thought about it. Let's say I had a world map of 200x200, which would actually be pretty small as far as RPGs go. That would amount to 40,000 Lists. To my mind I think there has to be a better way. Now this IS pre-mature optimization. I don't know if the way I happen to design my maps and game will be able to handle this, but it seems needlessly inefficient and something that could creep up if my game gets more complex. One idea I have is to make the offset and the multiple tiles optional so that I'm only paying for them when needed. But I'm not sure how I'd do this. A multiple array of objects? object[,] Grid; So here's my criteria: A 2D grid of tile locations Each tile location has a minimum of 1 tile, but can optionally have more Each extra tile can optionally have an x and y offset for pinpoint placement Can anyone help with some ideas for implementing such a design (don't need it done for me, just ideas) while keeping memory usage to a minimum? If you need more background here's roughly what my Map and Tile objects amount to: public struct Map { public Texture2D Texture; public List<Rectangle> Sources; //Source Rectangles for where in Texture to get the sprite public List<Tile>[,] Grid; } public struct Tile { public int Index; //Where in Sources to find the source Rectangle public int X, Y; //Optional offsets }

  • Do you know Best Practise and Design Patterns for Adobe Air/Flex Applications?

    - by Julian
    I'm going to write an application with the Air/Flex-Framework. I'm looking for Best Practise and general Design Patterns for designing software especially in Air/Flex. I have experience with this framework but never had the pleasure to write a piece of software from scratch. For instance: I stumbled across lots of software written in Air/Flex with nearly infinity global vars :-) Most of the software I saw was not object-oriented How can I pack the asynchronous method calls nicely? I'm familiar with general design patterns by gamma. I'm looking more for advise in designing good quality software with Adobe Air/Flex.

  • How to design parts of the application in XAML and how to reusing it then?

    - by MartyIX
    I'm working on a main window in my application and I would like to design parts of my window separately in Visual Studio designer. Main window Game desk (actually more of them and therefore it would be nice to design the game desk, mark it as a resource and then just via simple code (something like creating a new object and setting DataContext) create it. Console And so on Is it possible in VS to do this thing? I just need to know what to look for if it is possible. I don't need a whole solution. Thank you for suggestions!

  • Which is the best design practice for edit data in RIA?

    - by Onet Two
    Hi, First of all it is a UI design question! Which is the best design practice for edit data in RIA, for example in Flex or Silverlight? I would like to show customer's details, but there will be an edit window, than the datas of customer will be editable. I would like to show a new form where the data can be edited. What is the simplest way to show this form. I can make my ui tabbed, so I can open the form in a new tab, or I can open the form in a popup/modal dialog (Save-cancel). Maybe I can use in line editing. What is the most user friendly solution in a Silverlight or Flex GUI? What is your opinion? Thanks!

  • Is it acceptable to design my GLSurfaceView as a main control class?

    - by Omega
    I'm trying to structure a game I'm making in Android so that I have a sound, flexible design. Right now I'm looking at where I can tie my games rules engine and graphics engine together and what should be in between them. At a glance, I've been eying my implementation of GLSurfaceView, where various screen events are captured. My rationale would be to create an instance of my game engine and graphics engine here and receive events and state changes to trigger updates of either where applicable. Further to this, in the future, the GLSurfaceView implementation could also store stubs for players during a network game and implementations of computer opponents and dispatch them appropriately. Does this seem like a sensible design? Are there any kinds of improvements I can make? Thanks for any input!

  • Setting Ubuntu Global PATH for Ruby Enterprise Edition

    - by Wally Glutton
    Context: I recently installed Ruby Enterprise Edition (REE) on an Ubuntu 8.04 server. I would like for this new version of Ruby to globally supersede (for all users, crontabs, etc) the older version in /usr/local/bin. Attempted Solution #1: The REE documentation recommends placing the REE bin folder at the beginning of the global PATH in /etc/environment. I altered the PATH line in this file to read: PATH="/opt/ruby_ee/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" This did affect my PATH at all. Attempted Solution #2: Next I followed these instructions and updated the PATH setting in the /etc/login.defs and /etc/crontab files. (I did not change /etc/sudoers.) This didn't affect my PATH either, even after logging out and rebooting the server. Other information: I seem to be having the same problem described here. I'm testing using the command: echo $PATH My shell is bash. My .bashrc doesn't not alter my PATH. I'm ssh'ed into the system for all testing. /opt/ruby_ee/ is a sym-link to /opt/ruby-enterprise-1.8.7-2011.03/

  • I want to make video games, but I hate coding

    - by hoper
    I know this sounds eally crazy. However, I just want to ask. Now, I am studying C++ code in my school (My major is computer programming). Honestly, my grade is not so good, and assignments are really hard. Sometimes, I feel sad that I will spend 8~10 hours per day for coding (which is stressful) at the future for my job. But, I still want to make video games. Maybe this is the only one reason why I am taking all of stressful courses. I always write down plots, stories, characters, fictional gaming worlds. Once, I thought I should study artistic technology such as game design program not computer technology such as C++, C#, etc. However, most of popular game designers(or directors) such as Kojima, Miyamoto Shigeru, etc used to be good programmers. And, companies actaully assign programmers to directors because they understand how to make a game. I try to find other colleges or universities where teach game design program. However, one article that lists rank 10 game design schools in North America seems untrustful because the survey company only scores it from intervews of students. (Once, I tried to attend Art Institute of Vancouver which is rank 7 according to that article. However, one programmer who used to be an instructor in there told me the truth. That is the employement rate of graduated students is low) Do you guys have any advice for me?

  • Monster's AI in an Action-RPG

    - by Andrea Tucci
    I'm developing an action rpg with some University colleagues. We've gotton to the monsters' AI design and we would like to implement a sort of "utility-based AI" so we have a "thinker" that assigns a numeric value on all the monster's decisions and we choose the highest (or the most appropriate, depending on monster's iq) and assign it in the monster's collection of decisions (like a goal-driven design pattern) . One solution we found is to write a mathematical formula for each decision, with all the important parameters for evaluation (so for a spell-decision we might have mp,distance from player, player's hp etc). This formula also has coefficients representing some of monster's behaviour (in this way we can alterate formulas by changing coefficients). I've also read how "fuzzy logic" works; I was fascinated by it and by the many ways of expansion it has. I was wondering how we could use this technique to give our AI more semplicity, as in create evaluations with fuzzy rules such as IF player_far AND mp_high AND hp_high THEN very_Desiderable (for a spell having an high casting-time and consume high mp) and then 'defuzz' it. In this way it's also simple to create a monster behaviour by creating ad-hoc rules for every monster's IQ category. But is it correct using fuzzy logic in a game with many parameters like an rpg? Is there a way of merging these two techniques? Are there better AI design techniques for evaluating monster's chooses?

  • DAO/Webservice Consumption in Web Application

    - by Gavin
    I am currently working on converting a "legacy" web-based (Coldfusion) application from single data source (MSSQL database) to multi-tier OOP. In my current system there is a read/write database with all the usual stuff and additional "read-only" databases that are exported daily/hourly from an Enterprise Resource Planning (ERP) system by SSIS jobs with business product/item and manufacturing/SCM planning data. The reason I have the opportunity and need to convert to multi-tier OOP is a newer more modern ERP system is being implemented business wide that will be a complete replacement. This newer ERP system offers several interfaces for third party applications like mine, from direct SQL access to either a dotNet web-service or a SOAP-like web-service. I have found several suitable frameworks I would be happy to use (Coldspring, FW/1) but I am not sure what design patterns apply to my data access object/component and how to manage the connection/session tokens, with this background, my question has the following three parts: Firstly I have concerns with moving from the relative safety of a SSIS job that protects me from downtime and speed of the ERP system to directly connecting with one of the web services which I note seem significantly slower than I expected (simple/small requests often take up to a whole second). Are there any design patterns I can investigate/use to cache/protect my data tier? It is my understanding data access objects (the component that connects directly with the web services and convert them into the data types I can then work with in my Domain Objects) should be singletons (and will act as an Adapter/Facade), am I correct? As part of the data access object I have to setup a connection by username/password (I could set up multiple users and/or connect multiple times with this) which responds with a session token that needs to be provided on every subsequent request. Do I do this once and share it across the whole application, do I setup a new "connection" for every user of my application and keep the token in their session scope (might quickly hit licensing limits), do I set the "connection" up per page request, or is there a design pattern I am missing that can manage multiple "connections" where a requests/access uses the first free "connection"? It is worth noting if the ERP system dies I will need to reset/invalidate all the connections and start from scratch, and depending on which web-service I use might need manually close the "connection/session"

  • Today I talk about you

    - by BuckWoody
    Some time back I posted a blog entry (mirrored here and here) asking you how you design databases. Out of those responses, my own experience, studies I read, and interviews I conducted, I collected a wealth of data. Thanks for your responses. So what am I going to do with that information? Well, all along I had planned for that to be used today. I am giving a presentation at an event called “TechReady” called “How Your Customers Design Databases”. This is a Microsoft-internal event, where technical professionals like myself, salespeople, and the product team get together to talk about what has been working, what doesn’t, what is coming and hopefully (fingers crossed here) what the product team can do to help us help the SQL Server community. I’ve mentioned before that I teach database design as part of a course I run at the University of Washington. I’m also planning to give a mini-lecture from that series at TechEd 2010, so if you’re coming stop by. I’d love to meet you. So today I talk about you – thanks for the input. I hope you and I can make a difference in the product. Might take a while, but it’s nice to know your voice is being heard.

  • Can I become a Game Designer? [on hold]

    - by user32721
    This is my first time posting something on a forum in 4 years. I am posting this because I want to adjust my expectations and goals regarding game design. I am in college in Morocco (Al Akhawayn university). just started my junior year. I am a communications major (school of humanities) and a gender studies minor. I want to become a video game designer. It is the only career that I am interested in. I have been playing ever since I was 5 and haven't stopped yet. Currently I don't have any noteworthy skills to become a designer. I don't know how to program (don't really have the patience for it) and I can't draw to save my life. I haven't tried visual software like MAYA or MAX so I can't comment on graphic design. So I basically want to know whether my current education is capable of helping me reach my goal. If not then should I take a master's in game design (in the U.S?) or switch my minor to computer science? I am sorry that this post is long! I look forward to hearing your advice!

  • Library Organization in .NET

    - by Greg Ros
    I've written a .NET bitwise operations library as part of my projects (stuff ranging from get MSB set to some more complicated bitwise transformations) and I mean to release it as free software. I'm a bit confused about a design aspect of the library, though. Many of the methods/transformations in the library come with different endianness. A simple example is a getBitAt method that regards index 0 as the least significant bit, or the most significant bit, depending on the version used. In practice, I've found that using separate functions for different endianness results in much more comprehensible and reusable code than assuming all operations are little-endian or something. I'm really stumped regarding how best to package the library. Should I have methods that have LE and BE versions take an enum parameter in their signature, e.g. Endianness.Little, Endianness.Big? Should I have different static classes with identically named methods? such as MSB.GetBit and LSB.GetBit On a much wider note, is there a standard I could use in cases like this? Some guide? Is my design issue trivial? I have a perfectionist bent, and I sometimes get stuck on tricky design issues like this... Note: I've sort of realized I'm using endianness somewhat colloquially to refer to the order/place value of digital component parts (be they bits, bytes, or words) in a larger whole, in any setting. I'm not talking about machine-level endianness or serial transmission endianness. Just about place-value semantics in general. So there isn't a context of targeting different machines/transmission techniques or something.
